CAR HEATING AND VENTILATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 419,456, dated. January14, 1890.

Application filed March 2, 1889. Serial No. 801.748. (No model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES A. KIMPTON, of Malden, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Car Heating and Ventilating Apparatus, of whichthe following is aspecification.

It is the object of my invention to provide improved means whereby freshair, either heated or at its natural temperature, may be supplied to theinterior of a car or train of pipe or pipes containing heated air, and

valves for controlling the amount of air passing or that may be passedthrough said pipes.

Of the accompanying drawings, forminga part of this specification,Figure 1 represents a side elevation (parts being represented as brokenaway and parts shown in section) of a car equipped with my invention.Fig. 2 represents'a partial longitudinal section of a passenger-carfitted with pipes to receive air from the car shown in Fig. 1. Fig. 3represents a section on line so 00, Fig. 2. Fig. 4 representsa partiallongitudinal section of a passenger-car, showing a modification of thearrangement of the air-circulating pipes. Fig. 5 represents a section011 line so 0;, Fig. 4.

a designates a car, through which, near the roof, pass two pipes b c,the former communicating with the heater and steam-generator (1 throughthe medium of a connecting-pipe c, and with the pipe 0 through themedium of pipes f f and g, which are connected with the blower h.

1 and 2 designate valves in pipe I).

4 and 5 designate valves in pipe 0.

3 and 6 designate valves in pipe f, and 7 designates a valve in a pipe gwhich connects pipes f and f with pipe 0.

When the car is moved in the direction of the arrow marked on thedrawings, and it is desired to convey warm or heated air into a car orcars in the rear, valve 1 will be opened and valve 2 closed, so that theair entering pipe b will pass through connecting-pipe e to the heater(1, and through the coils '6 in the heater, where it will be heated.Valves 3 and 5 will be opened and valves 7, 4, and 6 closed, so that theair from the heatermay be'drawn by the blower h through pipes f f andforcedthrough pipe 9 out through the rear end of pipe 0. Should it bedesired to shut off the warm or heated air and convey cold or cool aironly to the carsin the rear, valve 3 will be closed and valve 7 opened,when the air will be drawn by the blower through pipes c and f andforced out as before.

When the car is moved in a direction opposite to that indicated by thearrow, and it is desired to convey air through and discharge it from thepipes in a direction opposite to that before described, if warm orheated air only is to be used, valves 1, 5, 6, and 7 will be closed andvalves 2, 3, and 4 will be opened, when the blower It will draw air inthrough pipe I), connecting-pipe e, the coil v. in the heater, andthrough pipes f f, and force it out through pipes g and 0. Should it bedesired to shut off the warm or heated air under the last-mentionedconditions and employ cold or cool air alone, valve 3 will be closed andvalve 6 opened, when the air will be drawn in through pipes c, f, and f,passing valve 6 and be forced out through pipes g and c, as before.

If it is desired to regulate the temperature of the air supplied to thecars by mingling cool air with the air which passes through the heaterwhen the train is moving in the direction indicated by the arrow, theValve 7 is opened to any desired extent, the valves 4 and 6 remainingclosed, as before. A supply of cool air from the pipe 0 is thus admittedto the pipe f and passes with the warm air from the heat-er through theblower to the cars. \Vhen the train is moving in the opposite direction,the same result may be produced by closing the valve '7 and opcnin thevalve 6. It will be SGQll,i)l101CfOl0, thatfresh air may be supplied tothe ears either at its natural temperature or raised to any desiredhigher" temperature within the capacity of the heater, so that the carsare thoroughly ventilated and may be easily kept at the desiredtemperature. The air thus supplied maybe distributed through thepassengercars by main pipes 1), extending lengthwise of the cars andcommunicating through suitable couplings c with the pipe r, said pipeshaving suitable outlets or branchespflthrough which the air isdischarged at numerous points into the car. (See Figs. 2 and Each of thebranches 1) is preferably pro vided with a valve 1', whereby the air maybe shut off, if desired, so that each passenger may control theadmission of air to his or her immediate vicinity.

If preferred, the longitudinal pipe 2) may be arranged on the floor ofthe car with its branches 1) under the seats, as shown in Figs. 4 and 5,in which case two pipes 17 should be en1ployedone at each side of theaisle.

Provision is made in the heater (Z for generating steam, which isconveyed through the medium of pipe j to the engine 7,:, from which,through the medium of belts and pulley the blower his operated, as mayalso be a d ynamoelcctric machine Z, by which electricity may begenerated for the purpose of lighting the cars.

It is to be observed that the valves of the several pipes may be soadjusted as that the heated and cool air may be forced through the pipesat the same time, and in any desired proportion with respect to eachother.

The contrivanee is simple in organization and may be constructed andoperated at comparatively low cost.

It is obvious thatchanges may be made in the form and arrangement ofparts without departing from the nature or spirit of the invention.

I claim- 1. In a car heating and ventilating apparatus, the combinationof a car, a heater, and a blower therein, a system of pipes or conduitswhereby external air is conducted through the heater to the blower andfrom the latter to a succeeding car, said system including a.

pipe to receive external air and conduct it to the heater, and a pipe 0,which extends through the car and is adapted to be opened to theexternal air at either end of the car, so as to introduce cold air orair at its natural temperature from either end of the car into theheated air in said pipes, and means for controlling or regulating thequantity of cold air thus admitted, as set forth.
